Ok here is the memory and kernel information it doesn't state PAE yet it seems to recognise the 32G.

[2] I am still confused how given the kernel reports as being
2.6.18-348.12.1.el5 #1 SMP and not a PAE kernel.. Why am I seeing MemTotal: 3574676 kBfree just outputs in kilobytes unless you pass it options.
So you're only looking at 3.5 GB of memory with a non-PAE kernel in CentOS 5 based on your numbers. Go PAE and you'll be able to utilize the 32GB of RAM.
# Megabytes free -m
# Gigabytes free -g
# any others options: man free
Doh.. thanks Mike .. consequence of working through the night I expect! Ok now just to decide if it is safe to run "centos 5" on the x79 motherboard.
